Electromagnetic induction heating 3D printing and forming system

Abstract

The invention relates to an electromagnetic induction heating 3D printing and forming system, and relates to the technical field of 3D printing equipment. By adopting an electromagnetic induction heating technology, the electromagnetic induction heating can realize high heating efficiency, energy conservation and environmental protection, so that the defects of low efficiency, high energy consumption and the like of resistance wire heating can be avoided. In addition, the electromagnetic induction heating is high in temperature and uniform in heating, controllable in heating speed and heatingtemperature, and relatively high in control sensitivity; next, by adopting an electromagnetic heating disk mode, an electromagnetic induction coil is wound into a disk shape, so that the overall structural size is small, and too much space of the forming system is not occupied; the invention provides circular, square, rectangular and fan-shaped electromagnetic induction coil winding modes, so thata thought is provided for the electromagnetic induction heating coil winding modes; and specific to different equipment structural characteristics, different winding modes can be selected, so that space can be utilized effectively, and heating uniformity is ensured.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to an electromagnetic induction heating 3D printing forming system. Background technique [0002] 3D printing technology is a technology based on the principle of discrete accumulation, integrated computer graphics processing, digital information and control, electromechanical control technology and material technology, and adopts the method of accumulating materials layer by layer to realize the technology of rapid free forming of parts. There are still a series of problems in industrial-grade metal 3D printing and forming. Due to the selective melting and forming process of high-energy beams such as laser / electron beams, the printed product is prone to deformation and cracking. When the product is printed in the first few layers, the temperature of the powder bed is low. The temperature of the molten pool formed by the high-energy beam is relatively high, forming a l...
